HPLC trace of IBA glucose conjugates of the extracts from the wild type (WT) and transgenic plants (OEs).
(+) and (−) represent the plant tissues incubated with or without IBA before extraction process. Peak “a” indicates the picloram added as an internal control at the beginning of the extraction process; Peak “b” indicates the IBA-glucose conjugates. The extracts were analyzed with a linear gradient of methanol in H2O from 10–70% (all solutions contained 0.01% H3PO4) over 30 min at 1 ml/min and monitored at 280 nm.
